A strike by air traffic controllers in Portugal has forced a number of airlines to cancel flights.
Portuguese air traffic control will be operating only a minimal service for 24 hours from 10pm on November 23.
The Portuguese flag carrier TAP said in a statement on its website that it will cancel “most” flights in Portugal and Europe.
The carrier plans to operate as many of its intercontinental services as possible, but schedules may change.
British Airways has cancelled all its flights to Lisbon on November 24, and brought forward its evening flight on November 23 (BA 504) by 30 minutes.
Ryanair cancelled the evening flight on November 23 from Stansted to Porto (FR8347), as well as some 50 flights to and from Portugal on November 24.
The walk-out of air traffic controllers is part of a general strike in the country, in protest against the government’s austerity measures.
It is the first strike in Portugal in more than three years.
Airlines were forced to cancel flights earlier this year due to strikes in Belgium, France and Spain.
